ADUs and lot splits
Moreno Valley requires every accessory dwelling unit lease to run 31 days or longer; short-term vacation rental is not a permitted use for an ADU.
For investors: An ADU in Moreno Valley only earns long-term rent, so underwrite it at monthly market rent rather than nightly rates. Write every lease for 31 days or more, including furnished stays for reservists or hospital staff.

Moreno Valley offers seven city-owned pre-approved ADU plans, from a 306-square-foot studio to a 988-square-foot three-bedroom, each with a required submittal template.
For investors: Choosing between the two-bedroom plans, 779 or 910 square feet, lets an investor size a backyard rental to the lot. A city-owned plan saves design time, but the plan page lists no fees, so get an estimate from the permit counter first.
